11.7.4 Grounding Conguration (with corner-grounded delta-input)

If one phase of delta-input source is grounded (B-phase for example), the ground bus in the UPS cabinet

should NOT be connected to the neutral terminal of UPS output.

The jumper cable should be removed see Figure 11.17 for the jumper cable location.

During normal operation the UPS output is oating relative to the ground. An isolation transformer is

recommended at output distribution as shown in Figure 11.20.
